Researchers working at the Advanced Light Source have discovered, in
three different families of high-temperature superconductors, "kinks"
in the energy spectrum of low-energy electrons  the signature
of coupling between electrons and phonons. Electron-phonon coupling accounts
for low-temperature superconductivity in metals and alloys, but most scientists
did not expect to find it in high-temperature, copper-oxide superconductors.

comparative
genomics at the JGI: an interview

Mice, puffer fish, sea squirts: what
do these creatures have to do with humans? To find out why scientists
are comparing their genomes  and those of many other creatures 
Science Beat interviewed Trevor Hawkins, director of the Joint Genome
Institute; Paul Richardson, JGI's head of functional genomics; and Dan
Rokhsar, JGI's head of computational genomics.

challenging
the standard model of physics

Z particles carry the weak nuclear force, and the measurement of their decay
spells trouble for the theory that has successfully explained fundamental
physics since the 1970s. A Berkeley Lab theorist argues that whether scientists
accept the measurement as valid or dismiss it as an anomaly, the
Standard Model loses.
